4 Claims. (01- 60-41) :This invention relates to an improved power generating system, and one of its objects is to provide means for generating power from rotating turbine units, and a power transmission means consisting of coupled turbine pumps, one of which is driven by the turbine unit means, and the other of which is a driver for any mechanism or vehicle driving means coupled therewith.

Another object of the invention is to provide a power generating system, which includes a series of combustion chambers, a turbine engine connected with each combustion chamber, an air tank, and a turbine compressor connected with the ai tank, together with connections between the air tank and a fuel supply for charging the combustion chambers with a fuel mixture.

With the above and other objects in view, the invention comprises certain new and useful constructions, combinations, and arrangements of parts, clearly described in the following specification, and fully illustrated in the drawings, in which:

Fig. l is sectional view through the main units of the system, showing the conduits connecting the units to each other.

Fig. 2 is a view through the housing forthe turbine pump units.

Fig. 3 is a vertical sectional view showing one form of a safety valve for the air receiver tank.

Fig. 4 is a similar view, showing another form of a safety valve for the air receiver tank.

Fig. 5 is a detail plan view of a drive shaft coupling.

Referring to the drawings, which illustrate the practical embodiment of the invention, 5 designates a main air conduit or pipe, in which an air filter i is installed. From this filter the air conduit 1 extends to the rotary or turbine compressor 8, and the air from this compressor is delivered by the pipe 9 to the air receiver tank Ill.

The air supply of the tank Hi is supplied to another compressor H, of the rotary or turbine type, and the air discharge from this compressor is conducted by the pipe I2 to heating coll i3, arranged in the large pipe 5. The coil I3 is connected to the manual valve I4, which is again connected with the feed pipe i5, which discharges into the primary combustion chamber l6. This combustion chamber is supplied with fuel from the pipe l!, which is connected with the fuel tank or source l8, through the valve l8, and is also connected by the branch pipe with the air tank I0.

2 the duct 2! to the turbine engine 22, the chat 22a of which is coupled to the shaft Ila of the turbine compressor II. The discharge from the turbine engine 22 is conducted by the pipe 22 to the fuel teed pipe 24 of the combustion chamber 25, and this chamber discharges by the duct 28 to the turbine engine 21. The shaft 28 or the engine 21 is coupled to the shaft 29 of the hydraulic transmission pump 30. Combustion chamber 25 is also provided with a control valve IS".

The turbine engine 21 discharges by the pipe 3| to the combustion chamber 32, which discharges by the duct 33 tothe turbine engine 34. the shaft 35 or which is coupled to the: shaft 3! of the turbine compressor 8.

Additional air is supplied to the combustion chamber I G by means of the pipe 31, which is equipped with a valve 38, and to the combustion chamber 25 by means of the valved pipe 39, and to the combustion chamber 32 by means of the valved pipe 40, from the pipe 31, which is supplied by the tank ID with pressure air. Combustion chamber 32 is likewise provided with a control valve I911.

The discharge from the turbine engine is conveyed by the exhaust pipe 4| to the heating tube orpipe 42, within the main air tube 5, and in this heating tube a baiiie 43 is arranged below the heating coil I 3, so that the coil 13 is thus supplied with exhaust heat.

When the air filter 6 becomes clogged up with dirt the valve 44 may be opened, on the air pipe 45, and a blast of scavenging air supplied to the discharge side of the filter.

The hydraulic transmission pump 30 is enclosed by a housing 46, which is filled with pressure oil or other fluid, and one side opening 41 of this pump is coupled to the valve housing 48 [by means of the conduit 49, and the other side opening or port 50 is normally open. The valve housing 48 is also coupled by means of the conduit 5| with a liquid operated motor 52 to be driven by liquid delivered under pressure from the pump 30. The valve 54 controls the amount oi! liquid passed from the pump 30 to the motor 52. The other port of this motor 52 is connected by the conduit 53 with the valve housing 48. In the valve housing a rotary valve 54 turns on the operation of the lever 55, which extends above the housing 46 and swings on the curved rack bar 56. A filler plug 51 is provided. The shaft 58 of the liquid operatedmotor 52 is coupled by the universal coupling joint 59 with the driven mechanism The combustion chamber ll discharges through combined with the power plant system, and not 3 here shown. The outlet port 59- is controlled by rotary valve 54 which is operated by lever 55 moving along the rack bar 56.

The capacity of the pump 30 may be increased by increasing the capacity of the motor 52.

The waste heat of one combustion chamber is utilized to raise the temperature developed in the second stage combustion chamber, and the waste heat thus produced in the second stage combustion chamber is utilized to raise the temperature in the third stage combustion chamber.

- The waste heat from the third stage combustion chamber is utilized to raise the temperature of the compressed air and fuel supplied to the primary turbine engine 22, through the primary combustion chamber I 6.

My system thus combines a series of combustion chambers, discharging into each other, and a series of turbine engines operating from these combustion chambers, and again operating primary and secondary turbine compressors.

The tank is equipped with a safety blow of! or pressure responsive relief valve 60, which comprises an intake tube 6|, the coupling nut 62,

and the valve housing 63, which is formed with a side port 63a, which is normally closed by means of the cylindrical valve 64, acted on by the compression spring 65. When the pressure in the tank exceeds the resistance ofiered by the spring 65, the valve 64 will be raised above the port 63a and the pressure will be relieved through venting through this port.

The tank in is also equipped with a second pressure responsive relieving valve which comprises the housing 66, which is formed with ports 6'! and 68, on the upper end thereof. In this housing the valve stem 69 slides, and carries the conical valve 10, to engage the conical seat H, under the pressure of the coil spring I2. When the pressure in the tank l0 exceeds the resistance of the spring 12 the valve will be lifted from its seat, and the pressure will be reduced until the resistance of the spring is suflicient to force the valve to its seat. One of these safety relief valves is to be provided with a weak spring and the other with a strong spring, so that one will yield when the minimum excess pressure is reached, and the other will yield when there has been a sudden rise in pressure beyond the capacity of the weaker valve.

All of the waste heat is utilized for a useful purpose to increase the efficiency of combustion. The power generated is transmitted to the driven mechanism, whether this be a vehicle or a stationary plant, by means of a hydraulic coupling, involving a large and a small pump.

Having described the invention, I claim as new the combination and arrangement of parts shown, and it is understood that various changes in the adjustment and details of construction, and their combination may be carried out, within the scope of the invention, as defined by the claims hereof.
